Ensure that the specific driver for your sensor/chip is enabled in your .config under the normal Device Tree drivers section.

A more philosophical debate surrounds the use of PRP0001 . Some kernel maintainers view it as a "workaround" that should only be a last resort. The preferred approach for standard hardware is to use proper ACPI IDs to maintain a clean, idiomatic ACPI description that is compatible with other operating systems. As one kernel developer noted, using PRP0001 is "not idiomatic ACPI" and other OSs actively reject the idea of binding to devices described this way. However, proponents argue that it's a pragmatic solution that enables significant code reuse without breaking anything.

Parsing the _DSD for PRP0001 devices adds cycles. On a real-time embedded system with tens of pseudo-devices, disabling PRP0001 can shave tens of milliseconds from the boot sequence – critical for safety-critical initialization.

ACPI is the standard for device discovery, power management, and configuration in x86 systems (and increasingly ARM servers). When a PC boots, the BIOS/UEFI provides the OS with ACPI tables (DSDT, SSDT, etc.). These tables contain AML (ACPI Machine Language) bytecode that describes every device on the motherboard: PCIe slots, UARTs, I2C controllers, GPIOs, and more.

The Linux kernel parses these tables and creates platform devices, PCI devices, or ACPI-defined devices accordingly. Each device in ACPI has a unique – a string like PNP0501 (legacy serial port) or INT33BD (Intel I2C controller).
